The aim of this study was to obtain a quantitative analysis of the film thickness of a root canal sealer formed after filling by three different techniques. Thirty human maxillary incisors were selected and access cavities were prepared using high-speed diamond stones and water spray. A size #15 K-Flexofile was introduced in the canal of each specimen until it was seen just at the apical forame...

This in vivo study evaluated the sealing ability of a resin-based sealer (AH Plus) and a zinc oxide-eugenol sealer (Endofill) in dogs' teeth, exposed to the oral environment for 45 and 90 days. Forty eight lower incisors from 8 dogs were endodonticaly treated. A stratified randomization determined the sealer use in each root canal. All canals were filled using the lateral condensation technique...

INTRODUCTION The purpose of this study was to assess the effect of different irrigation protocols for smear layer removal on the bond strength of EndoSequence BC Sealer, a new bioceramic sealer, to root canal dentin. MATERIALS AND METHODS The middle third of forty-four extracted human teeth were sectioned horizontally to obtain 128 dentin disks. After standardization of canal spaces, dentin d...

INTRODUCTION The function of root canal fillings is to seal the root canal system. The important physical property necessary for sealers to achieve this is low solubility. However, any therapeutic effect of calcium hydroxide-based sealers is dependent on the calcium hydroxide being in ionized form, which implies that the material must be at least partly soluble. OBJECTIVE The objective of our...

The aim of this study was to evaluate the physical properties of EndoRez, Diaket, Epiphany, Roekoseal, Fibrefill, GuttaFlow, AHPlus, AH26 to that of a traditional zinc oxide based Kerr PCS sealers. Ten samples of each material were evaluated for flow, radiopacity, solubility and dimensional change tests according to ISO standards 20016876. The findings were statistically analyzed. Radiopacity a...

The essential steps for successful endodontic treatment consist of elimination of all diseased pulp and dentin tissues, adequate chemomechanical preparation and filling of the root canal system hermetically.[1] Moreover, it is crucial that root canal obturation has to be limited within root canal system. Minor apical foramen or minor apical constriction is known to be situated 0.5–1.5 mm corona...

OBJECTIVES The aim of this in vitro study was to compare the efficacy of two retreatment rotary systems in the removal of Gutta-percha (GP) and sealer from the root canal walls with or without solvent. MATERIALS AND METHODS Forty-eight extracted human mandibular first premolars were prepared and obturated with GP and AH Plus sealer. Samples were then randomly divided into four groups. Group I...

AIM To assess the presence of Enterococcus faecalis after root canal treatment in single or multiple visits in an ex vivo model. METHODOLOGY Forty-five premolar teeth were infected ex vivo with E. faecalis for 60 days. The canals were then prepared using a crowndown technique with System GT and Gates-Glidden burs and irrigated with 2% chlorhexidine gel. The specimens were divided into five gr...

The sealing ability of orthograde mineral trioxide aggregate (MTA) root canal filling against human saliva was assessed in vitro. Leakage of gray-colored MTA, white-colored MTA and vertically condensed gutta-percha and sealer were compared. Forty-three extracted single-rooted human teeth were serially instrumented to a file size 40/0.06 at the apex and obturated with either gray-colored MTA (gr...

To study the adhesion of epoxy resin based endodontic sealers by determining the tensile bond strength and evaluating the effect of smear layer removal on the adhesion of the endodontic sealers. Root canals of freshly extracted mandibular first premolar teeth with single root canal, were instrumented by using rotary instrument The roots were prepared for adhesion by splitting them and embedding...
